Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional three-dimensional camera platforms are bulky and require significant material reinforcement for rigidity, which compromises their compactness and light weight, leading to potential image distortion due to mechanical compliance during dynamic operations or adjustments, affecting the precision of stereoscopic images.
Innovation Solution
A compact camera platform design featuring a first and second support wall connected at right angles, with a fixed camera connector, an adjustable camera connector, and a beam splitter support frame, allowing for precise alignment and adjustment of dual cameras while minimizing material usage and maximizing rigidity and light weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional beam splitter support structures are used with two main support plates connected at a point far from the mounting area, then the structural stability is maintained, but the platform becomes bulky and requires significant material reinforcement
Solution Approach 1:
The patent repositions the beam splitter support frame from the interior quadrant to the exterior space between the outer surfaces of the support walls. This dimensional relocation allows the support structure to leverage the existing wall geometry for rigidity while reducing the volume occupied by the platform itself, eliminating the need for excessive material reinforcement
2Strength
If significant material and external gusseting are used to reinforce the support structure, then the rigidity between cameras is improved, but the platform weight increases
Solution Approach 1:
By moving the beam splitter support frame to the exterior space between the outer surfaces of the support walls, the design utilizes the structural geometry of the walls themselves for reinforcement. This eliminates the need for additional gusseting and heavy material, achieving camera rigidity without increasing platform weight
Solution Approach 2:
The patent extracts the beam splitter support function from the interior quadrant space and relocates it to the exterior space between the support walls. This separation allows the support structure to be achieved through the existing wall geometry rather than adding redundant reinforcement materials, reducing overall weight while maintaining rigidity
3Volume of moving object
If the beam splitter support frame is located inside the quadrant, then the compactness is improved, but the structural rigidity is compromised
Solution Approach 1:
The patent resolves this contradiction by relocating the beam splitter support frame to a different spatial dimension - specifically, the exterior space between the outer surfaces of the support walls rather than the interior quadrant. This positioning maintains compactness by utilizing available external space while achieving structural rigidity through the geometric relationship with the support walls

AI summary
A camera platform for three dimensional photography comprises a first support wall having an inner surface, an outer surface and a fastening end, and a second support wall having an inner surface, an outer surface and a fastening end. The first and second support walls are connected to each other along at least a part of their respective fastening ends so as to be substantially at right angles to each other. The inner surface of the first support wall and the inner surface of the second support wall define a quadrant. A fixed camera connector is formed on the outer surface of the first support wall for connecting to a first camera, and an adjustable camera connector is formed on the outer surface of the second support wall for connecting to a second camera. A beam splitter support frame is provided for holding a beam splitter, and the beam splitter support frame is located outside the quadrant between the outer surface of the first support wall and the outer surface of the second support wall.
